Monday's start to the legal tampering period produced a lot of noise and some actual news: Howie Roseman took a look at some of what Chip Kelly did in his brief tenure as the Eagles' head personnel man, and decided those weren't players that he wanted to keep. Linebacker Kiko Alonso and cornerback Byron Maxwell went first, to the Miami Dolphins. Later in the day, Adam Schefter broke the big deal, DeMarco Murray to the Tennessee Titans. Neither deal can officially be completed before the new League Year begins on Wednesday.

It seemed likely. It made a lot of sense. And now it's official: Peyton Manning will announce his retirement Monday at a press conference in Denver. He finishes his career as the NFL leader in passing yards, passing touchdowns, sack rate, game winning drives, comebacks, and internet arguments spawned over team vs. individual greatness. He topped our passing DYAR and DVOA metrics six times each in his career and had eight more seasons ranked second or third in DYAR.

It's the offseason, so you have time to read scheme pieces if you so desire. Fran Duffy of the Philadelphia Eagles' website, who does consistently good work and is a good draft follow as well, has a great piece breaking down Jim Schwartz's defense, with plenty of clips from Detroit and Buffalo of how it's supposed to work.

In this week's NBC/SNF feature, I became the latest person to write about Green Bay's offensive struggles this year, focusing on some of the numbers. For some of the tape behind what's gone wrong, see for instance Greg Cosell's piece on some of what went wrong against the Cardinals.

Interested in who would make the playoffs under each potential tiebreaker scenario? The post linked, put together by commenter Travis, has all the different AFC possibilities, while this one has all the NFC possibilities. The AFC chart is a good explanation of why Jacksonville is at only 8.6% in our playoff odds despite being just a game back of Houston and Indianapolis: they'll need at least one Titans win or a Colts-Texans tie.

The Houston Texans are making their first appearance on Sunday Night Football this season, so I made another attempt to put J.J. Watt's dominance in some recent and historical perspective. Naturally, he now has a cast on his left hand/wrist and did not practice on Thursday.

In advance of the Steelers playing the Colts, this week's NBC piece looks at Antonio Brown. ICYMI, he's really good and does a lot of things really well, though Todd Haley may be calling too many wide receiver screens.

In this week's piece for NBC Sports, I go into more detail on Joe Goodberry's insight that Andy Dalton performs much better against teams the Bengals have not faced recently. Potentially good news for a bounceback on Sunday night against the Cardinals, and potentially very bad news yet again in the postseason.

In case you haven't noticed, the undefeated Packers are playing the undefeated Broncos on Sunday Night Football this week, and a couple 6-0 teams meeting up is kind of a big deal. So, I wrote a couple pieces about it.

Column #1, linked above, is about the Packers ranking third in most penalties through Week 6 after they were flagged for the third-fewest penalties last year, and just how big a deal that is likely to be.
